FRANCIS S. 11160, OF LOS ANGELES, CALIFORNIA.

TWIN BED.

Application filed October 22, 1914.

To all whom it may concern:

Be it known that I, FRANCIS S. INoo, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Twin Bed, of which thefollowing is a specification.

The invention relates to spring beds, and particularly to those bedswhich are adapted to be used by two persons simultaneously, these bedsbeing commonly called double beds in the trade.

Many beds have been devised for this purpose but they are ordinarilyobjectionable in that when two persons occupy them there is a tendencyfor the bed to sag in the middle and thus throw the two personstogether.

The principal object of the invention is to provide a double bed whichwill be free from this central sagging tendency, so that it may beoccupied with perfect comfort by two persons, each person occupying hisown side and thereby enjoying all the comfort of a single bed.

A further objection to many double beds is that where they are occupiedfor long periods by a single person alone, the spring becomes distorted,sagging downwardly in the center, thereby unfitting the bed for a doubleoccupancy if it is later desired to use it for this purpose.

A further object of the invention is to provide a bed spring which willbe free from this tendency to sag in the middle so that it may beoccupied by a single person for long periods without undue distortion.

Further objects and advantages will be evident hereinafter.

In the drawings, which are for illustrative purposes only: Figure 1 is aplan view of a bed spring, a portion thereof being omitted. Fig. 2 is apartial section on the plane w w of Fig. 1. Fig. 3 is a partial sectionon the plane m w of Fig. 1. Fig. 4 is a partial section on the plane maa of Fig. 1.

In the embodiment of my invention illustrated in these drawings, a frame10 is provided consisting of longitudinal pipe members 11 which areconnected through castings 12 to cross bars 13 which extend entirelyacross the bed, the members 11, 12 and 13 forming a rigid and permanentframework of any desired dimension. Located on either side of the centerof the bed are right and left hand net works 14 and 15, these net worksbeing of inelastic construction and Specification of Letters Patent.

consisting of wire members formed into short links 16 and long links 17the short links being used in the body of the net work and the longlinks being used to produce straight edges thereof. Centrally located inthe bed is a center strip 18 which is partially elastic and which ispreferably formed of spring members woven together to form aninterlocked web. Located on either edge of the bed are edging strips 19and 20 similarly formed from wire springs and preferably having a roundshape as shown in Fig. 4. The strips 18, 19 and 20 are rigidly securedto the cross bars 13 by means of clips 21 and rivets 22. Secured inholes 23 in the cross bars 13 are a series of helical tension springs24, one end of these springs being fastened to the cross bars 13 throughthe holes 23, and the other end of the spring being formed in an eyeover which the ends of the links 16 and 17 are looped. The inelastic netwires 14 and 15 are secured to the elastic strips 18, 19 and 20 by meansof tie wires 25, these tie wires being secured at either end to thesprings 24 as shown at 26 and passing longitudinally of the bed, beinglooped througa the strips as shown at 27 and through every fourth jointof the net work as shown at 28 so that the net works 14 and 15 aresecured to the strips 18, 19 and 20 by these tie wires 25. It will benoted that the tie wires are run very nearly straight so that there canbe a slight longitudinal motion of the net works 14 and 15 with relationto the strips 18, 19 and 20. The springs 24 are made of such a strengththat the net works 14 and 15 yield under the weight of the body, forminga comfortable bed and this yielding is considerably in excess of that ofthe members-18, 19 and 20, although these members yield somewhat whenweight is applied thereto. The result is that while it is possible for aperson to sleep across the strip 18 there will be relatively littleyielding of this strip as compared to the yielding that would take placewere the net works 14 and 15 formed in a continuous series without thestrip 18. It will be seen therefore that the invention consists broadlyof two inelastic net works elastically supported to the end cross bars,these net works being separated by an elastic strip which is rigidlysecured to the cross bars in such a manner that the natural tendency ofthe center of any spring to sag is corrected by the insertion of therelatively unyielding central strip.

The invention further consists in two net works of any kind separated bya central strip, the central strip being less elastic than the two networks, so that each net work is free to yield separately withoutaffecting the other.

I claim as my invention A twin bed spring comprising a frame havingcross bars extending across each end of the bed, a partially elasticcenter strip secured at each end to the center of one of said crossbars, an edging strip of partially elastic construction secured betweensaid cross bars at each edgeof the spring right Copies of this patentmay be octained for and left inelastic net works each located be tweensaid center strip and one of'said edging strips, means for elasticallysecuring the end of each net work to said cross bars, and

'means for slidably securing said net work to said center and edgingstrips.

In testimony whereof, I have hereunto set my hand at Los Angeles,California, this 16th day of October, 1914:.
